A8- OUTPUTOVERLOADAND SHORTCIRCUIT
PROTECTION
To prevent permanent damage to the GS-D500A,
three protections have been implemented against
overloadand short circuits between:
- outputto output
- outputto ground
When one ofthese adverseconditions occurs,the
driver of the output H-bridges is disabled for about
500ms and the condition is signaled by the FAULT
signal.
A9 - FAULT SIGNAL
The FAULTsignal is availableat pinJ3-13. When a
fault is present, pin13 goes low versus pins 6,7.
Whenever the FAULT signal is activated, the led
providedin thefrontedge ofthe moduleis switched
ON.
The FAULT signal is active (low) when:
- the supply voltage is lower than 12V
- the heatsinktemperatureis higher than 90
°
C
- an output overload is present
- a disableis active.
